Product Description
Suitable for single and three phase supply, the Din Type Single Pole Switchable Fuse Switches is manually operated to switch load between power supplies. Customers prefer it to switch from electric power supply to the stand-by supply, thereby ensuring consistent power generation. Operated manually, this switch has the flame retardant body to prevent the chances of accidents due to short-circuiting and over voltage conditions. The purpose of demanding this switch is to allow consistent electricity swapping from the generator to supply and vice versa. It is extensively used in almost every commercial and residential place for handling the current of up to 63 amperes. We procure quality assured materials to manufacture this Din Type Single Pole Switchable Fuse Switches.
